Abstract
INTRODUCTION: Dancers experience high training loads in training and do not currently have a viable method of measuring external load. Dancers often experience symptoms of overuse as well as an increase in musculoskeletal pain with higher training loads. Previously, PlayerLoad (PL), from an inertial measurement unit (IMU) worn on the upper back, has been observed to increase as intensity and RPE increase in dancers.
PURPOSE: To measure tibial load and load fluctuations during a period of standard dance classes classes as well as assess how PL and RPE relate to these measures.
METHODS: A wearable IMU was secured on both ankles of two participants using the manufacturer supplied silicon strap. Data was collected across five distinct sessions of a weekly modern or ballet dance class. The participants were then asked to report their RPE for that class. PL was calculated via a custom Python script.
RESULTS: PL per minute on the dominant leg varied between both participants across their five sessions (Range: 5.49-8.21; 4.73-10.1). PL per minute during treadmill walking was substantially higher (18.67, 23.22). Total high impact peaks (>20 g) per minute varied between both participants (Range: 0.176-0.400; 0.019-0.036) with both substantially higher than treadmill walking (0.00).
DISCUSSION: This pilot study found that PL per minute correlated poorly with RPE in dancers while high impact peaks per minute did seem to correspond with RPE. Future research could possibly focus on high peaks or other measures that correlate with RPE such as heart rate.
